Raw hazard in computer architecture
WebThere are three situations in which a data hazard can occur: read after write (RAW), a true dependency; write after read (WAR), an anti-dependency; ... In computer architecture, a transport triggered architecture (TTA) is a kind of processor design in which programs directly control the internal transport buses of a processor.

As instructions are fetched, control logic determines whether a hazard could/will occur. If this is true, then the control logic inserts no operations (NOPs) into the pipeline. Thus, before the next instruction (which would cause the hazard) executes, the prior one will have had sufficient time to finish and prevent the hazard. If the number of NOPs equals the n… slurry consistencyWebThe dependencies in the pipeline are referred to as hazards since they put the execution at risk.
